Abstract: A new growth curve model has been established, namely the generalized Usher model, which is more flexible and adaptable. The model has been applied for prediction of production and recoverable reserve of Samatelore oilfield. Application result demonstrated that such a model could be used to describe the developing procedure of some things or events, and the resulted matching accuracy is no less than that of commonly used Usher model.

Key words: model, prediction, oilfield, production, recoverable reserve
